4SPECIFICATIONformingpart of Letters Patent No. 279,119, dated June 12,1883. Application filed February 9,1853. (Model.)

To all whom, llt/'may concern:

Be it known that I, MONROE BARNES, a citizen ofthe United States,residing at Bloo1nington, in the county of McLean and State of Illinois,have invented certain new and useful Improvements in Corn-PlanterCheck-Bowers and I do hereby declare the following to be a full, clear,and exact description of the invention, suoli as will enable othersskilled in the art to which it appertains to 1n ake and use the saine,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to corn` planter oheck rowers of that class inwhich a tappet-wire stretched over the ground to be planted is used foractuating the seed-slides through the in` strumentality ofa forked leverwith which the tappets on the wire come in contact, and the inventionrelates Inore especially to that subdivision of this class ofcheck-rowers in which the forked lever swings in a horizontal plane, andthe invention consists in a novel manner of hanging and swinging thewire-retaining pulleys, for t-he purpose of doffing or freeing the wirefrom the planter.

The invention further consists in a novel means for operating theswinging pulleys, all as hereinafter described.

In the accompanying drawings, which illustrate my invention, and inwhich the similar letters used as marks of reference apply to the` likeparts in all the figures. Figure 1 is a top plan. Fig. '2 is a sideelevation. Fig. 3 is a rear elevation.

In the drawings I haveonly shown one set 0f. the devices used at one endof the ordinary supporting-bar, A, which bar is to be attachedtransversely on the planter, as usual, and has a similar set of devicesat its other end.

Referring to the drawings by letters, B is an ordinary plate, secured tothe end of the bar A.

C is an ordinary.elbow-shaped lever, journaled or pivoted at c, so as toswing in a horizontal plane, and forked at its outer endfor thereception of the tappet-wire D, and for the action of the tappets d,which are secured thereto. Froin the inner end'of the lever C a rod orlink, E, extends to any suitable mech anism for actuating the seedslides of the planter.

F F are grooved guide-pulleys, journaled on studs, one near each endofthe plate B, and so as to rotate in or about in horizontal planes.

G l' are retaining-pulleys, cylindrical in form, and each with anannular iiange, y, at its upper end, which flange, however, may bedispensed with. v

H H' are elbow-shaped levers, journaled at their bends to studs 71,which project upwardly from each end of the plate B.

The pulleys G G are jonrnaled, one to the outer end of each elbow-shapedlever, on studs l1', so as to rotate in or about in horizontal planes. Arod, I, is hinged at one end to the inner end of the lever H, and asimilar rod, I', is hinged at one end to the lever H'. The adjacent endsof the rods I I' are connected by a pivot bolt or pin, J, at a shortdista-nce from the end of each rod. The *rod Ihas downwardly-projectingpins i', one on each side ol' the pivot J, and the rod I' has slots i"in one side, one on each side of the pivot J, and at same distances fromsaid pivot, respectively, as are the pins i'. The pivot-pin J extendsabove the rods I I', and a cord, K, is secured thereto, which extends tothe dri vers scat on the planter. IV h en the rods I I' are in positionsas sh Own by full lines in the drawings, the elbowshaped levers H H willbe heldthereby, as shown, in such positions as to bring the pulleys G Gsome what back past the flanges of the pulleys F F', so that thetap'pet-wire will be held in the grooves of said pulleys F F by theretainingpulleys G G', as shown at Fig. 3, and thereby guided so thatthe tappets d will properly act on the forked lever C and swing itsouter end rearward in the direction ofthe arrow shown at Fig. l.. Theforked lever is returned to its nor- Inal position by a spring, c', inthe ordi-nary manner. W'hen the rods I I are in the positions lastdescribed, the pins i will rest in the slots ri and lock the rods I I',so that the pulleys G G cannot be swung toward each other by any forceto which they are subject in use, acting on either or both of saidpulleys; but the driver, by drawing on the cord K when the planter`reaches the end of the rows, will thereby pull the rods I I',elbow-shaped levers H H', and pulleys G G into the respective positionsshown by dotted lines at Fig. 1, and the pulleys G G', thus drawn awayfrom the pulleys F F', will doff the tappet-wire or free it from theplanter IOO without requiring the driver to get off his seat.

, When the planter isturned around for a new bout, the tappet-wire maybe again placed in the grooves in the pulleys F F' and the rods I I' andlevers H H' again moved into the posi` tions shown Yby full lines, tobring the retailiing-pulleys G G' into place to keep the tappetwire inproper' working position.

I do not claim herein, broadly, any method of swinging the pulleys G G',which rotate in horizontal planes, away from grooved pulleys F F',whichrotate in similar' planes, as such invention is the subject of a pendingapplication made j ointly by mysel fwith Alden Barn es; butn v That Iclaim, and desire to secure by Letters Patent, is

l. In a checlcrower, in combination with the tappet-wire and elbowshapedlever, and grooved pulleys F F', journaled on vertical axes, thecylindrical pulleys G G', journaled also on vertical axes carried onelbow-shaped levers H H', which Swingin horizontal planes,substantiallyas and for the purpose specified.

2. In a check-rower, in combination, the tappetwire, lforked lever,grooved'pulleys F F', journaled on vertical axes, elbow-levers H H',also journaled on vertical axes, and carrying cylindrical pulleys GG',which swing with said elbow-levers in vertical planes, substantiallyas and for the purpose specified.

In combination with the tappet-wire,v

forked lever, horizontal rotating pulleys F F', andpnlleys G G', carriedon elbow-shaped levers H H', the' rods I I', pivotally connected to theelbow-shaped levers and to each other, and adapted to act-uate saidelbow-shaped levers to swing the pulleys G G', substantially as and forthe purpose specified.

4. In a check-rower, in combination with the swinging elbow-leversI-IH', carrying pulleys, the rods I I', pivotally connected to said leversand to each other, and one of them provided with pins i' and the otherwith slots i", whereby they may be locked to prevent action on thepulleys moving them, substantially as and for the purpose specified.

5. In combination with the tappet wire, forked lever, grooved horizontalpulleys, and the cylindrical pulleys carried on swinging elbow-shapedlevers, the rods I I', provided with pins i' and slots i", respectively,by means of which said rods may be' locked, substantially as and for thepurpose specified.

In testimony whereof I afix my signature in presence of two witnesses.
